4 Claims.

My present invention relates to sliding band bracelet constructions, andhas particular reference to a novel construction for the lower band.

It is the principal object of my invention to provide a slide bandconstruction for preventing tarnish or stain when the bracelet is wornon the wrist.

Another object of my invention is to provide a simple arrangement bymaintaining the two bands of a slide band bracelet from contacting eachother along substantial areas.

An additional object of my invention is to provide a spacing arrangementfor the two bands of a slide band bracelet, which may be economicallyand quickly applied.

Still another object is to provide a spacing arrangement which does notdetract from the appearance of the bracelet, and which blends into andforms part of the bracelet design.

With the above and other objects and advantageous features in view, myinvention consists of a novel arrangement of parts more fully disclosedin the detailed description following, in conjunction with theaccompanying drawing, and more specifically defined in the claimsappended thereto.

In the drawing:

Fig. 1 is a plan view of a slide band bracelet equipped with my novelarrangement;

Fig. 2 is a side view thereof:

Fig. 3 is an enlarged detail on the line 33 of Fig. 2, parts beingbroken away;

Fig. 4 is a view of the reverse side of. the bracelet details shown inFig. 3;

Fig. 5 is a section on the line 5-5 of Fig. 4;

Fig. 6 is a section on the line 6-6 of Fig. 4; and

Fig. 7 is a perspective view of a novel spacer according to myinvention.

It has been found that bracelets having their bands formed of an outerlayer of precious or semi-precious metal such as solid gold or goldplate, which is secured to or is wound on a flexible core strip of adifferent metal, such as for example stainless steel wire mesh, becomesstained or tarnished when subjected to perspiration and the like.Although the reasons for such staining or tarnishing are not defiinitelyknown, there seems to be a local electrical action between the diiferentmetals of the bracelet, apparently in the nature of a localelectrolysis, or possibly a local action of perspiration on the metalsin combination with a local electrolysis. The local action may bebetween the core strip material, such as stainless steel, and thecovering or outer layer of precious or semi-precious metal, or may evenbe, in the case of plated metal, between the outetr plate and its basemetal. This staining or tarnishing is particularly found when theprecious or semi-precious covering metal is in the form of contiguousstrips, either wound around a flexible core, or secured at their ends tothe core edges. Whatever the cause may be, it has been found thatstaining and tarnishing are prevented if the two bands forming slidableband bracelets are kept out of direct contact. To this end, I haveprovided a novel spacer arrangement, which preferably forms part of thelower band, and which effectively spaces the lower band from the upperband when the bracelet is worn on the wrist, thus preventing thestaining and the tarnishing above described.

Referring to the drawing, which illustrates a preferred construction,the novel slidable band bracelet I0 is composed of an upper band H and alower band 12, one end [3 of the upper band being provided with an endhook l4 for securing to a watch bail, the other end 15 being providedWith a securing element 16 which is preferably of the snap type and isadapted to be releasably locked to a buckle H, the buckle being slidablymounted on the lower band l2 and adjustably positioned along the lengththereof.

One end I8 of the lower band has an end connector loop [9 through whichthe upper band freely passes, the other end 20 of the lower band havingan end hook 2| for securing to the other watch bail of a wrist watch orthe like. The releasable connector elements, the buckle, the end hooks,and the slide loop l9, may be of any desired construction.

Each band preferably includes a core strip 22 of flexible material, thepreferred material being stainless steel in the form of wire mesh,although other materials such as for example thin lead strip may beused, an ornamental outer covering or layer 23 of solid or platedprecious metal, such as solid gold, or gold on a nickel base, beingformed on the core strip as by securing narrow lengths of precious metalor plated metal 24 to the core strip; the illustrated construction hasthe ends 25 of adjacent outer layer strips clamped or rolled to firmlyengage the edges of the core strip as illustrated in Fig. 4. If desired,the strips 24, instead of being separate as illustrated, may be in theform of a continuous length which is spirally wound around the corestrip 22.

Referring now to Fig. 2, it is evident that the two bands when assembledhave the lower surface of the upper band and the upper surface of thelower band in close adjacency, thus bringing the metal layer strips 24into close adjacency to the core strip material. With this type ofconstruction, perspiration or the like has a tendency to produce stainsand tarnish; and I therefore provide spacer elements 26 having raisedbars 21 at spaced intervals on the upper surface of the lower band whicheffectively prevent contact of the two bands over any substantial area.

My preferred construction for the spacers 26 is illustrated in Fig. '7,the spacers 26 being narrow strips of precious or plated metal eachhaving an integral longitudinal raised bar 21, which are positioned atspaced intervals between the strips 24, the ends 28 of the spacers 26being looked over the edges of the core strip, as by gripping orrolling, so as to effectively secure the spacers 26 at spaced intervalson the upper surface of the lower band l2 as illustrated in Fig. 3. Thespacers 26 are of narrow width, and are preferably of the same materialas the strips 24; they are preferably wider, but may be indented, asindicated at 29, to simulate the narrower strips. They therefore blendinto the ornamentation of the bracelet surface itself, and are notdisclosed when the bracelet is worn, as they are hidden between the twobands.

Instead of using separate spacers such as illustrated in Fig. 7, certainof the strips 24 may, if desired, be formed with longitudinal ribs orbars to obtain the same separation between the upper and lower bands ofthe bracelet. Or the spacers may be secured in any suitable manner tothe upper band so as to extend from the lower surface thereof. If thespiral winding type of covering is used, the ends of the spacers arepreferably locked to the edges of the wound band.

While I have described a specific constructional embodiment of myinvention, it is obvious that changes in the relative size and shape ofthe parts, in the details of construction of the two bands, and in thematerials used for the two bands, may be made to suit the requirementsfor different bracelet designs, without departing from the spirit andthe scope of the invention as defined in the appended claims.

I claim:

1. In a bracelet construction comprising an upper band and a lower bandslidable endwise one upon the other for shortening or lengthening thebracelet, a lower band having spacer bar sections at spaced intervalsalong the upper surface thereof to prevent contact of said two bands.

2. In a bracelet construction comprising an upper band and a lower bandslidable endwise one upon the other for shortening or lengthening thebracelet, a lower band having spacer bar sections comprising narrowbands having central raised portions having their ends secured to saidlower band at spaced intervals along the upper surface thereof toprevent contact of said two bands.

3. In a bracelet construction comprising two bands slidable endwise oneupon the other for shortening or lengthening the bracelet, a braceletband having spacer bar sections at spaced intervals along the surfacethereof contiguous the other band to prevent contact of said two bands.

4. In a bracelet construction comprising two 5 bands slidable endwiseone upon the other for shortening or lengthening the bracelet, abracelet band having spacer bar sections comprising narrow bands havingcentral raised portions having their ends secured to said band at spacedintervals along the surface thereof contiguous the other band to preventcontact of said two bands.
